Case Study: Listrak achieves effortless email scaling with Bird PowerMTA

How Listrak uses PowerMTA to scale up sending effortlessly

Listrak, a digital marketing platform for retailers, needed a more scalable outbound email sending solution as its homegrown MTA approach hit throughput limits and lacked strong reporting, injection rates, and a delivery dashboard. The company was growing quickly and needed a way to handle high-volume email sends more reliably across 1,000+ clients.

Bird, using PowerMTA, replaced Listrak’s patchwork infrastructure with a highly configurable, scalable MTA environment that let the team manage queues, automate back-off, and make changes without downtime. The result was effortless scalability and improved performance, with Listrak now sending 1 billion emails per month and dedicating VMTAs for most customers to maintain reliability.
